Charging Model: volvo high frequency machine is a microprocessor (CPU microarrays) as process control center ESD5550, is complicated hardware analog circuit programming in microprocessor ESD5330, by way of a software program to control the UPS operation. Therefore, much smaller ESD5500E, greatly reducing the weight of ESD, low manufacturing costs, the price is relatively low. High Frequency inverter frequency generally 20KHZ above, but high-frequency machine in harsh environmental conditions of the grid and tolerance poor, is more suitable for the grid more stable and less dust, temperature / humidity environment suitable charger Model: 3634778 desulfurization desulfurization charging charging concept: When the battery improper use or maintenance, such as charging less frequently, over discharge or discharged When long-term placement in the battery plates will be formed a large, hard lead sulfate crystals, this "curing" of the battery, the conventional charging method, it is difficult charged electrically, must use a special method for charging desulfurization charging. ? Connect the charger and the battery charging plug; ? Turning the power grid; ESD5500 | Zhongxin Electrical and Mechanical (certified) | ESD provided by the Dongguan City, South City Zhongxin Electrical and Mechanical Services Department.
